Unformatted text preview: Question 4 ) v3.1 Question 4: Hydroboration of an alkene followed by oxidation (H 2 O 2 , OH-) is one of the useful method for alcohol synthesis. In order to synthesize the secondary alcohol ( H ) in an efficient way, what alkene structure you would suggest? Give your reasoning. (10 points) (H) OH 1. BH 3 , THF 2. H 2 O 2 , HO-H 2 O Answer: (fill the alkene structure in the box provided) Question 5: In the radical chain polymerization process, a benzoyloxy radical adds to an unsymmetrical alkene to form the more stable radical such as ( I ). Hyperconjugation and inductive effect of the alkyl group (CH 3 ) are used to account for the radical stability. Fill in the box provided below the structure of radical ( J ) and give your reasoning. (10 points) (I) BzO BzO + H 2 C C CH 3 CH 3 H (J) BzO + H 2 C C H Answer: [end]...
